...Due to the nature of using the frequency domain, data augmentations in this area are generally used for sound recognition, e.g. EMDA has been used for acoustic event detection [74] and animal audio classification [75] and SFM has been used for speech [56]....

...Empirical Mode Decomposition (EMD) [102] is a method of decomposing nonlinear and non-stationary signals and it has shown to improve classification by using it as a decomposition method for data augmentation of noisy automobile sensor data in a CNN-LSTM [103]....

...In order to obtain meaningful instantaneous frequency, restrictive conditions have to be imposed on the data as discussed by Gabor (1946), Bedrosian (1963) and, more recently, Boashash (1992): for any function to have a meaningful instantaneous frequency, the real part of its Fourier transform has…...

...Therefore, the parameter, ν, defined as N21 −N20 = 1 π2 m4m0 −m22 m2m0 = 1 π2 ν2, (3.7) offers a standard bandwidth measure (see, for example, Rice 1944a, b, 1945a, b; Longuet-Higgins 1957)....
